Details of the poke event announcement. There has been an idea to scouring a cute keyboard. Before I had seen Lofei Dot Bluetooth mechanical keyboard in the shopping mall, we planted grass. Just when Ma Shushu had an activity, it was decided to pick it up. Remove from the courier box, there is a plastic seal outside the box. The plastic side has charge support tips. Then open the plastic seal. Then take out the envelope of the keyboard, it is the box itself After opening the box there is a layer of black foam containing the keyboard body and the right side is the accessory box. Remove the contents of the box, in addition to the keyboard itself also has a USB cable, warranty card and instructions. The connector is the same as the Android phone's interface. The keyboard is surrounded by rounded corners. The pink buttons are round. Look closely. The workmanship is general. The material is plastic polishing. What should be used for office typing should be no problem. If you play the game, it is not very suitable. This keyboard uses a green axis that is suitable for office typing. The near point can be seen that the size of the keyboard is not the standard size, the key position is more dense, and it takes time to adapt The side can see the space bar is the use of the design of the satellite axis, press it will be more stable than the balance bar. There are four fixed feet on the back of the keyboard. The height of the keyboard is fixed and not adjustable. It is said to be a specially designed 6-degree tilt angle that can relieve wrist pain. Side from left to right are the system match switch keys, you can switch between win/android and mac/ios mode, there are Bluetooth switches, you can connect three at the same time, fn+1/fn+2/fn+3 free to switch devices, The far right is the USB interface. Built-in 4000mAh lithium battery lasts for two weeks. Since I'm a mac system, switch the mode switch to the right and turn on the bluetooth switch. Here the LED white backlight of the keyboard is on. Feel the brightness of the lower backlit keyboard background brightness ~ brightness can be adjusted, there are three brightness, the brightest one off the light when there will be a little glare, the keyboard will enter a dormant state after standing for some time, you want to use When you touch a certain key, it will light up.

Press and hold the 3 second key combination fn+1 to activate the Bluetooth pair code (the capitalization indicator is flashing). Mac system, click on the settings in the computer, select the keyboard, and then click on the Bluetooth keyboard in the lower right corner, this time the interface will automatically identify DOT@LOFREE. Click Pairing to complete the connection You can start to use friends ~ pink keyboard and before the Amoy pink egg mouse also looks quite right on the keyboard to play the word to have a ticking sound, louder, more pick the environment to use; button sink feel is obvious, Not used to the mechanical keyboard may feel that the button is a bit "hard", but like the retro typewriter will like this tactile typing experience the keyboard as a whole has a certain sense of weight, not suitable for carrying, more suitable for use on the desktop.
